Earthquake strikes Russia's Kamchatka Peninsular

A powerful earthquake of magnitude 7.8 has struck off Russia’s Kamchatka Peninsular with its epicentre near Alaska’s remote Aleutian islands.
The quake was very shallow, only 10 km below the seabed, which would have amplified its effect, but it was far from any mainland and there were no immediate reports of any casualties or damage.
It was followed by numerous after shocks , some above 5.0 magnitude.
